Arduino uno, dht11, ssd1306, humidity display (No.3)

 It is important to maintain the relative humidity in your room. It is said that maintaining 40~60% is good. If it`s too low, it will have some damage to your skin and your breathing. When it`s too high, there`s a higher the room might become moldy. 

And there`s a relation between feels like temperature and the humidity. It says that as humidity rises 10%, the feels like temperature also rises around 1℃. It is because, when the humidity is high, the less water evaporate from your skin. 

I installed this system because in winter the room tends to get dry, and made it as an indicator in order to humidify.

Let`s get into the project. 

Materials 

1. Arduino uno

2. dht11 

3. ssd1306

Dht11 is a sensor that detects, relative humidity and temperature. I used ssd1306, it is called Organic LED display. It creates a beautiful color compared with LCD display.
